Differential Air Pressure Sensor Wireless LoRaWAN NB-IoT Wireless Option:NB-IoT and LTE CAT-M 32°F-158°F (0°C to 70°C) PowerDifferential Air Pressure Sensor Wireless LoRaWAN NB IoT Sometimes it is not necessary to monitor the absolute air pressure but we need to know the difference of pressures in different points. One example may be before and after a valve in a pipe. If the valve is fully open, the pressure on both sides should be the same. If there's a difference in the pressure, it could be the valve isn't fully open or there's a blockage. Differential Pressure Sensor
